The special feature of the XL sniffer adapter is that it generates a very high gas flow of 3,000 sccm: a key requirement for dynamic robot leak detection. Only with a high gas flow can even small leak rates of 1 x ^10-4 mbar∙l/s, for example, be detected at all when scanning a component using the escaping test gas. At the Inficon stand, the company will be demonstrating dynamic robotic leak detection using a housing as the test part.

Higher process speed

Inficon has designed the modular LDS3000 leak detector specifically for use in industrial production. The LDS3000 uses either helium or the cost-effective forming gas, a non-flammable mixture of five percent hydrogen and 95 percent nitrogen, as tracer gases. The Protec P3000XL leak detector also draws in escaping tracer gas at a high flow rate of 3,000 sccm and can therefore also be used for robot sniffing. However, the combination of LDS3000 and XL sniffer adapter allows even higher process speeds, as the LDS3000 uses different, optimized signal processing algorithms.

The principle of sniffer leak detection - whether by robot or manually - is that the measuring tip draws in air (and test gas) at a certain flow rate. The common unit for this gas flow is sccm (standard cubic centimeters per minute). Many conventional sniffer leak detectors draw in gas with a particle flow of only 60 sccm. With careful manual handling of the sniffer tip at only a few test points and with slow movement at a short distance from the surface, this can sometimes be sufficient. However, dynamic robotic sniffer leak detection in particular places much higher demands. Only devices with a very high gas flow - such as those from Inficon with 3,000 sccm - are capable of reliably detecting the escaping tracer gas. They do this even when the robot arm moves the measuring probe over the test part at speeds of ten centimetres per second and more. as
